Back in the old neighborhood we were discussing sleep difficulties.
I started taking a multi-vitamin with whatever was suggested (lycopene?) and started cutting back on caffeine. About two weeks ago I was totally off caffeine (other than an occasional chocolate), yesterday I had a couple Diet Cokes... tossed and turned all night.
Back on the wagon today

LOL, Skinny-- it seemed to fit Spud-- no headaches this time but a few years ago when I went off caffeine I did. I've never been a heavy caffeine user but all it takes to mess up my sleep cycle is one serving about seven or eight hours before hitting the pillow

Even with no coffee post-mid afternoon, I have started waking up around 1-2 am simply because body and mind are in over-drive. Part of the reason is the associated heat generation and the bloody tempur-pedic mattress not dissipating that heat fast enough.

The best sleep aid I've found; meditating before going to bed. A simple 5 or 10 minutes, doing my best to be quiet and/or reflect on the past day. I always wake up feeling better than I would if I didn't.

We recently got sucked into the Sleep By Number cult. I have to admit, I am sleeping better than I have in years. Significantly less tossing & turning and deeper sleep as a result.

That's the good side. Bad side - the cost is ridiculous. Sure, the base model is comparable to a similar, "normal" bed.....until you see what you get. The "box spring" is just a bunch of blow-molded parts that are press fit together and the "mattress" is a zippered case with foam edges to hold the form and two air mattresses inside. Their margin has to be ridiculous of those things.

But I certainly can't argue with the results - I'm definitely sleeping better.
